Is it permissible to stand before people in the mosque and supplicate for them with the intention of treating anxiety and lack of self-confidence, and not with the intention of inviting to Allah?

Whatever affliction befalls a Muslim is a test from Allah, either to raise their ranks or to expiate their sins. Do not surrender to anxiety; rather, seek its causes and treat them. Know that benefit and harm are in the hand of Allah alone, and He is most worthy of your fear and hope. If you find that calling people to Allah removes your anxiety, then do so with a sincere intention for Allah. Accustom yourself to righteous company, especially with those who offer good counsel.

Among the tips for overcoming anxiety: 1. Having a good opinion of Allah and trusting Him: Seeking refuge in Him and relying on Him dispels anxiety and removes turmoil. Supplication is the weapon of the believer; it repels and removes affliction, so be keen on times of answered prayers. 2. Be confident that your problem is treatable: This depends on your sincere desire for change and taking the necessary means. 3. Seek help from educational and administrative books: Those that teach organizational skills and how to deal with anxiety and shyness. 4. Consult a specialized psychiatrist: Especially those who are righteous and religious, for Allah may benefit you through them.
